Recent Results on Light-Meson Spectroscopy from COMPASS
/ Wallner, Stefan (Munich, Tech. U.)
/COMPASS Collaboration
The main goal of the spectroscopy program at COMPASS is to explore the light-meson spectrum below about $2\,\text{GeV}/c^2$ in diffractive production. Our flagship channel is the decay into three charged pions: $p + \pi^-\to \pi^-\pi^-\pi^+ + p_\text{recoil}$, for which COMPASS has acquired the so far world's largest dataset of roughly $50\,\text{M}$ exclusive events using an $190\,\text{GeV}/c$ $\pi^-$ beam.

The $t$-dependence of the pure DVCS cross section at COMPASS
/ Joerg, Philipp (Freiburg U.)
/COMPASS Collaboration
The key reactions to study the Generalised Parton Distributions are Deeply Virtual Compton Scattering (DVCS) and Deeply Virtual Meson Production (DVMP). At COMPASS, these processes are investigated using a high intensity muon beam with a momentum of 160\,GeV/c and a 2.5\,m-long liquid hydrogen target. [...]

Photons interacting with Hadrons at COMPASS
/ Friedrich, Jan Michael (Technische Universitaet Muenchen (DE))
/COMPASS NA58 Collaboration
COMPASS is a multi-purpose experiment operated at CERN for investigations of the strong interaction from low to medium energy scales. At low energies, photon-pion interactions provide input for understanding the effective dynamics of strongly bound states of quarks and gluons, most prominently the recent measurement of the polarisability of the charged pion.
